Tom Chalk
Thomas Chalk is a researcher at the Centre Nationale de Recherche Scientifique (CNRS), in Aix-en-Provence, France. He specializes in environmental science and palaeoclimatology using geochemical tools. He uses geochemistry as a tool to reconstruct and understand modern environments and past climate, notably including proxies based on the element boron and its isotopes. With this he has a strong research focus on the reconstruction of ancient pH and atmospheric carbon dioxide. He is also interested into how calcifying organisms are impacted by climate change, and/or how they can influence Earth’s climate themselves. Thomas uses experiments in the laboratory and the field to try and better understand the links between the ocean, climate, and carbonate minerals.
